摘要
河北宽城崖门子剖面长城系下统(常州沟组、串岭沟组和团山子组)页岩中微古植物丰富多样,保存完好,其中尤以串岭沟组最佳。经鉴定总计17属63种,包括5个新种。这进一步揭示了长城系下统各组微古植物的特征,亦为上述各组的空间分布和对比提供了有力的古生物依据。
The Middle and Upper Proterozoic strata are widespreadly distributed in Kuancheng County of the eastern Hebei Province. The lower series of the Changcheng system in the representative Yamenzi section is completely developed with continuous sequences. Microflora form the shale facies are well preserved diversified in species and genera. There are 63 identified species from 17 genera including 5 new species as follows: Dictyosphaera fasciata (sp. nov.), Leioarachnitum longplicatum (sp. nov.), Leioarachnitum simplex (sp. nov), Scaphita rugosa (sp. nov.), Trachyarachnitum Incrassatum (sp. nov.).
